Description

an oil removal filter

technical field

The utility model relates to the technical field of oil removal equipment for air compressors, in particular to an oil removal filter.

Background technique

Compressed air is a kind of power source, and it is the power source of various pneumatic tools and pneumatic equipment; but compressed air itself often contains fine oil, water and dust, and the damage of these things to pneumatic equipment cannot be ignored. It may even cause tools and equipment to be scrapped in advance; therefore, it is necessary to purify compressed air more effectively.

Existing high-efficiency compressed air degreasers, the air-water separation devices for removing liquid moisture mainly include cyclone separation type and baffle wire mesh combination type. For the cyclone separation type, the compressed air enters the separator along the tangential direction from the upper pipe of the pressure vessel, and the centrifugal force generated by the high-speed cyclone is used to realize the centrifugal separation of air and water, but it cannot separate the mist beads with small mass in the air flow, so that the subsequent stage can remove oil The load on the filter element is increased, and the life of the filter element is shortened; for the baffle wire mesh combination type, the compressed air enters the separator along the intake pipe, and is first hit by the baffle set in the direction of the inner wall of the shell, and the water droplets mixed in the air stick to the surface of the baffle and Larger droplets that accumulate on the edge of the baffle fall into the bottom of the separator, and then the airflow rises through a filter made of multi-layer stainless steel wire mesh, and the tiny droplets condense and grow to get further separation , although the separation effect has been improved, but the airflow resistance is large and the height of the device is high.

Utility model content

In order to solve the above problems, the utility model provides an oil removal filter with reasonable structure design, good oil removal effect, high oil removal efficiency, long service life and small footprint.

The utility model adopts the following technical solutions:

An oil removal filter, comprising an upper shell and a lower shell, the upper shell and the lower shell are connected by flanges, and the outer walls of the opposite sides of the upper shell are respectively provided with an air inlet and an air outlet , the top of the inner cavity of the upper casing is located between the air inlet and the air outlet, and a partition plate extending downward is provided. One end of the partition plate is welded to the top of the inner cavity of the upper casing, and the other end of the partition plate One end extends into the lower casing, the upper casing is provided with a first wire mesh filter plate at the position below the air inlet and the air outlet, and the second wire mesh filter plate is arranged at the position of the extension of the partition plate in the lower casing , the top of the second screen filter plate is provided with a fine filter element, the bottom of the second screen filter plate is provided with a baffle plate, and several small holes are evenly distributed on the baffle plate, and the bottom of the lower shell is provided with a drain valve .

As a preferred technical solution of the present invention, the first wire mesh filter plate, the second wire mesh filter plate and the partition plate are all made of stainless steel.

As a preferred technical solution of the present utility model, the first wire mesh filter plate, the second wire mesh filter plate and the fine filter element are respectively nested on the separation plate, and the outer periphery of the first wire mesh filter plate is welded On the inner wall of the upper shell, the outer periphery of the second screen filter plate is welded on the inner wall of the lower shell.

The beneficial effects of the utility model are:

The utility model has simple structure and reasonable design. A partition plate is arranged in the upper casing to divide the inside of the casing into two chambers, and the air inlet and the air outlet are respectively located in different chambers, so that the size of the casing does not change. At the same time, the flow path of the gas is increased, so that the gas filtration program is doubled, and the oil removal rate of the gas can be effectively improved while ensuring that the oil removal filter occupies a small area.

detailed description

Now in conjunction with accompanying drawing, the utility model is described in further detail.

As shown in Figure 1, an oil removal filter includes an upper casing 1 and a lower casing 2, the upper casing 1 and the lower casing 2 are connected by flanges, and the opposite sides of the upper casing 1 An air inlet 3 and an air outlet 4 are respectively arranged on the outer wall, and a partition plate 5 extending downward is provided on the top of the inner cavity of the upper housing 1 between the air inlet 3 and the air outlet 4, and the partition plate One end of 5 is welded to the top of the inner cavity of the upper casing 1, and the other end of the partition plate 5 extends into the lower casing 2, and the partition plate 5 divides the interior of the upper casing 1 into two independent chambers , and the air inlet 3 and the air outlet 4 are respectively located in different chambers, the upper housing 1 is provided with a first screen filter plate 6 at the position below the air inlet 3 and the air outlet 4, and the lower housing 1 2. A second wire mesh filter plate 7 is arranged at the extension end of the partition plate 5, a fine filter element 8 is arranged above the second wire mesh filter plate 7, and a baffle plate 9 is arranged below the second wire mesh filter plate 7. , There are several small holes evenly distributed on the baffle plate 9, and the bottom of the lower casing 2 is provided with a drain valve 10.

The first screen filter plate 6, the second screen filter plate 7 and the partition plate 5 are all made of stainless steel.

The first wire mesh filter plate 6, the second wire mesh filter plate 7 and the fine filter element 8 are respectively nested on the partition plate 5, and the outer periphery of the first wire mesh filter plate 6 is welded to the upper casing 1 On the inner wall, the outer circumference of the second screen filter plate 7 is welded on the inner wall of the lower casing 2 .

Concrete principle of the present utility model is as follows:

The compressed gas enters the degreasing filter from the air inlet 1 and then passes through the left side of the first screen filter plate 6, the left side of the fine filter element 8, the left side of the second screen filter plate 7, and the second wire mesh filter plate. The right side of the mesh filter plate 7, the right side of the fine filter element 8 and the right side of the first wire mesh filter plate 6 perform multiple filtrations, which can effectively remove the oil and moisture in the gas, and finally the gas flows out through the gas outlet 2 ; The filtered oil and water flow into the bottom of the lower shell 2 along the inner wall of the shell or the partition plate 5, and finally are discharged out of the shell by the drain valve 10.
